The great spreadsheet in the sky
How blockchain could solve some of the world鈥檚 problems.
Blockchain technology has the power to change all kinds of things for the better.
If that power is harnessed, it has the potential to end corruption, protect your online identity and a whole lot more. Start-up companies and charities are using it in everything from tuna supply chains to medical records and ID documents and everything in between. This week People Fixing the World explores whether its great potential can be realised.
